To all whom it may concern.-

Be it known that we, OLIVER PETERS and DE HAVEN M. Lnvrs, citizens ofthe United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania,"

have invented'certain new-and useful Improvements in ReversibleSign-Boards, of p provided with a pin b which is: inserted and which thefollowing is a specification.

Our invention relates to new and useful improvements in reversible sign-boar'dsf of the type more specifically used upon streetrailway cars;and it consists of a novel means for turning the sign-board andafter ithas been turned the required distance looking it securely in position.

Our invention, which embodies novel details of construction in devicesof this character, will be more fully understood by reference to theaccompanying drawings, in which- Figure 1 illustrates a front elevationof a sign-board constructed in accordance with our invention. Fig. 2represents an enlarged vertical section of the sign-board, taken on theline 2 2 of Fig. 1, with a portion of the top broken away. Fig. 3illustrates a'vertical section similar to Fig. 2, taken on the line 3 3of Fig. 2; and Fig. 4 represents an enlarged horizontal section taken ontheline 4 at of Fig. 3.

Referring to reference-letters of the drawings, A represents thesign-board, B, the

' shaft or supporting-rod; G, the bearing by which the shaft is carried,and D. a portion of the roof of a car or framework to which the bearing0 is fastened.

The sign-board A, which, it will be under stood, may contain on eachside the name of the street denoting the direction in which the car ismoving or its destination, is detachably secured to the rod B by eithera set-screw or, what is better, a spring-pin a asillustrated in Figs. 1and 2. The'board 'A is provided with a plate A, fastened by screws f,and the pin a above referred:to,,p"asses through the plate A and entersan opening b, in the rod B. When the pin a is in engagement with the rodB, it is held in place by a spring a so that the sign A will turn withthe rod B. When it is desired to remove the sign-board and replace it byanother, as is often necessary when the route of a car is changed, the

pin a is pulled outward against the action of thespring a and the boardis then free to be removed.

The bearing 0 comprises a casting provided 5 5 fixed in an opening inthe rod through a hole o in the castingO. When the rod-B is in a lockedposition, the pin b rests in notches 0 c in the casting O and isretained in position by a spiral spring"S,which surrounds the rod B andis confined-between the bottom of the casting O and a collarR, thelatter being fastened to the rod B by a pin 4. The lower recess 0"serves to permitcentr'al clearance for the shaft B, so that the supportfor the shaft will take place at the top and bottom of the bearing 0, lThe lower end of the rod B is provided with a handle B fastened by ascrew b The sign board is operated as follows: When it is desired toturnthe board, the operator grasps the handle Bo and presses it upwardagainst the action of the spring S. This presses the pin 1) out of thenotches 0 0 and allows it to turn in-the upper recess 0. The operatornow turns the handle B and ceases topress the samefupward. The rod maynow be turned a half-revolution, when the action of the spring S willcause the pin b -to enter the notches e and'lock the rod B againstturning.

Having described our invention, what we claimQa'nd desire to secure byLetters Patent,

ing to receive the pin, 'a sign-board detachably secured to the upperend of the shaft, a

handle to turnthe shaft and means for re-- taining the pin in engagementwith the notches, substantially as described.

2. A reversible sign-board, comprising in I combination, a support orbearing having an opening to receive a vertical shaft and hollowed outat the top and bottom to form a In testimony whereof We affix oursignatures in presence of two witnesses.
